HAIR-TONIC APPLICATOR.

Application filed February 17, 1925.

My invention relates to a device for applying; tonic's and the like tothe scalp and hair of a person, and it is object to provide such adevice which of simple, durable and inexpensive construction.

A further object is to provide a manually operated applicator havin thegeneral form nf a comb;

A further object is to provide such an applicator which is provided witha container for the tonic or liquid used in connection therewith, and adelivery pipe havting a series of spaced nozzles to eject the liquid,and a control valve for said delivery pipe situated for convenientaccess to the hand of the operator.

A. further object is to provide such an applicator having a casingprovided with individual sleeves enclosing the delivery pipe nozzles,together with a resilient hand bulb adapted to supply air under pressureto said casing, the ends of the sleeves being, provided with exhaustopenings, so positioned adjacent the ends of the discharge nozzles thatthe action of the air escaping therethrough under pressure from thehandle will atomize the liquid within the discharge pipe and convey itthrough said exhaust openings.

Another object is to so form the ends of the casing sleeves that thedelivery of the liquid may be so controlled as to permit its beingdeposited either directly against the scalp or upon the hairs atadistanceabove the scalp.

Another object is to provide certain novel features of constructionwhereby the hand bulbmay bereadily removed and the opera tiveparts ofthe applicator readily made accessible for cleaning or repair, andwhereby the device may be constructed in a simple and inexpensivemanner.

/Vith these and other objects in View, my invention consists in theconstruction, arrangement andcombination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawng in wh c I i Fig. 1 is: an elevation. of the.applicator.

of hard rubber, and at one end is cast integrally with the comb portionof the appli- .ator, which I will indicate generally by the referencecharacter, 11, and which is preferably formed of sheet metal. Theportion 11 includes a liquid delivery pipe, 12, having the dischargenozzles, 18, and embedded at one end in the casting, 10.

The pipe, 12, is preferably formed of tubing, the nozzles, 13,being'tubesof fine bore, swagcd or soldered into the wall of the tube,12. The liquid chamber, 1 1, is formed between the walls of a plate ofsheet metal, doubled upon itself, as at 15, to form the container sides,16, which are thence bent inwardly, as at 17, and soldered to the sidesof the tube, 12, and thence extended dow11 wardly, as at 18, to form theair casing. The tube, 12, serves to separate the chamber, 14:, from theair casing, 18. 1

The nozzle sleeves are formed by splitting the metal extendingdownwardly from the air casing, 18, and thence drawing the edges of thesevered portions inwardly against the edges of the adjoining portions onthe other side, as at 19. I have used the refer ence character 20 toindicate the sleeve por' tion formed on one side of the casing, 18, andthe numeral 21. to indicate the adjoining; sleeve portion.

A tongue is formed on the portion, 21 and bent inwardly against the endedges of the sleeve portions to form an end wall 22. l Vhen the casingis completed the end wall, 22, is inclined as shown in Fig. and isprovided with an opening, 23, substantially aligned with the nozzle, 13.The advantages of so inclining the ends of the sleeves will later benorefully explained.

To give the applicator a finished appear ance two dummy teeth, 2% and25,. may be formed at the extremity of the comb portion thereof.

T he. lower edges of the casing portion, 18, between" the nozzle.sleeves and between the tooth, 25,, and-the casting, 1'0, well'as heouter. nds otth e wail-ls. .11 a d thet o r.

till

2 are drawn together to form a closed structure. The entire member, 11,may then be soldered to close the joints, or cleaned and dipped in anenamel coating of a coating of rubber composition. This is neces sary inorder to render the appli ator sanitary.

The outer end of the tube, 12, is solde ed or swaged into the end wallof the member, 11, as shown in Fig. 2, and a threaded plug, 26, servesto close the tube and to allow cleaning thereof.

The cavity, 27, in the casing, 10, communicates by means of a threadedopening, 98, with a duct, 29, which to? s a continuation of the tube,12.. A, neck, 30, having a threaded opening at its upper end co cateswith the cavity, 2'7, and is normally closed by plug, 31, threadedthereinto. liemoval of the plug,.-31, allows filling of the container, ll. I

The casting, 10, is bored and tapped to receive a threaded valve member,having a lower conical end seating against the shoulder formed betweenits threaded portion and the smaller threaded opening, 28. Thus, thevalve member serves to close or control the passage of liquid throughthe opening, 28, and may be removed to allow cleaning thereof. Cleaningof the pass n leading from the cavity, '27, to the opening, 28, may beetiected through the neck, 80, and cleaning of the tube, 12, and thepassage leading therefrom is facilitated by the lengthening of the duct,29, beyond the opening, 28, to allow a cleaning tool to extend beyondthe opening, 28.

The casting, 10, is provide with a handle portion, 33, paraboloidal inshape, as shown in .Fig. 5, and provided with the reduced neck portions,34, and 35, spaced to receive the ends of a rubber bulb, 36.

Into the end, 35, is threaded a cap, 37, which serves both to retain thebulb, 36, in place and to enclose a check valve, 38, in the passage, 39,which communicates with a passage, 40, in the handle portion, 33,allowing the entrance of air through the pas- 39, into the bulb, 36. Anopening, 41, provides communication between the bulb, 36, and the aircasing, 18, and is provided at its discharge end with a check valve,

It will now be seen that after filling the chamber, 14, with liquid, aquantity thereof may be allowed to escape into the delivery pipe, 12. Bycompressing and releasing the bulb, 36, a current of a' may be createdthrough the enclosing sleeves and the liquid drawn through the tubes,13, similar to the act-ion of the ordinary atomizer.

In order to allow entrance of air into the chamber, 14, to replace theliquid the plug, 31, is provided with a passage, 43, which may beclosedwhen the applicator is not in use. By tightening the plug, 31,

the neck, 30, and thus sealing the hamber, l l, the liquid will be eflectually ealed within the container and leakage will be prevented.

The tubes, 13, are of such gauge that the liqui fl will not pass throughthem cx pt when the pipe, i2, is in communication with the atmospherethrough the opening, 333.

By applying the tips of the sleeves to the scalp with the comb tilted soas to allow a liat conta't or". the end walls, with 2 scalp, it will beseen that the liquid. may be ..p 'ctl directly to the scalp. lly tiltingue comb in the other direction, at an angle J the scalp, and allowingthe extreme tips conta t with the scalp, the openings. ill-l. therebyraised fr m the scalp and dited laterally with respect thereto, theiquid may be sprayed among the hairs at 'dauce from the roots thereof.

will be understood that my applicator y be used for various purposesaside from of applying hair tonics and hair oils. as for shampooing ordyeing the hair.

Some changes may be made in the con struction and arrangement of theparts ot my invention without departing trom the real spirit and purposeof my invention, and it is my int 'on to cover by my claims any modinedforms structure or use of mechanical equivalents which may be reasonablyincluded within their scope.
